[PATCH v2] KVM: VMX: disable SMEP feature when guest is in non-paging mode

e the page table is set with USER flag. If SMEP is still enabled in this case, guest will meet unhandlable page fault and then crash. Signed-off-by: Dongxiao Xu Signed-off-by: Xiantao Zhang --- arch/x86/kvm/vmx.c |8 1 files changed, 8 insertions(+), 0 deletions(-) diff --git a/arch/x8

[PATCH v2 0/4] nested vmx code clean up and restructure

handle_vmread() and handle_vmwrite() functions. Thanks, Dongxiao Dongxiao Xu (4): nested vmx: clean up for vmcs12 read and write nested vmx: clean up for nested_cpu_has_xxx functions nested vmx: use vmcs12_read/write() to operate VMCS fields nested vmx: use a list to store the launched vmcs12

[PATCH v2 2/4] nested vmx: clean up for nested_cpu_has_xxx functions

This is a preparation for the later change, which use vmcs12_read() and vmcs12_write() to replace the way to access vmcs12 fields. Since the above functions uses 'vcpu' as parameter, we also use 'vcpu' as the parameter in nested_cpu_has_xxx functions. Signed-off-by: Dongxi

[PATCH v2 3/4] nested vmx: use vmcs12_read/write() to operate VMCS fields

When referencing vmcs12 fields, the current approach is to use "struct.field" style. This commit replace all the current solution by calling vmcs12_read() and vmcs12_write() fucntions. Signed-off-by: Dongxiao Xu --- arch/x86/kvm/vm

[PATCH 0/4] nested vmx code clean up and restructure

This patch series clean up and restructure part of the nested vmx code. The main purpose is to abstract the vmcs12_read() and vmcs12_write() functions. With this change, we have a unified API to get/set field values from/to vmcs12. Thanks, Dongxiao Dongxiao Xu (4): nested vmx: clean up for
